Security screening is a process used to check individuals and their belongings for prohibited items, ensuring safety in various environments like airports, events, and government buildings. This typically involves the use of metal detectors, X-ray machines, and manual inspections to identify weapons, explosives, or other dangerous materials. The goal of security screening is to prevent threats and maintain a secure atmosphere for everyone. It is an essential part of travel and public safety, helping organizations like the Transportation Security Administration (TSA) enforce regulations and protect the public from potential harm.
